SELF-INKING HAND-STAMP.

Application file October 7, 1914.

T 0 all whom it may concern:

Be it known that we, HARRY S. FoLGnR and CASPER L. Rnnrnznn, citizens ofthe United States of America, and residents of Chicago, county of Cook,and State of Illinois, have invented certain new and useful Improvementsin Self-Inking Hand- Stamps, of which the following is a specification.

Our invention relates to self inking hand stamps and has for its objectimprovements in the construction and operation of such stamps.

In the accompanying'drawings Figure 1 is a front elevation; Fig. 2 is asideelevation; Fig. 3 is a section on line 33 of Fig. 1; Fig. 4 is asection on line 4-4 of Fig. 1; Fig. 5 is a section on line 5 5 of F ig.2; Fig. 6 is a section similar to Fig. 3 but with the stamp moved to itsprinting position; Fi 7 is a perspective view of the swinging pac -boXsupporting framegand Fig. 8 is a perspective view of the pad box.

The sliding stamp holding frame 10 consists of a bail shaped piece ofsheet metal having a handle 11 at the center of the upper bridge. Thelower ends of the legs 12 of the frame 10 are connected together by abridge 13. Through the upper portion of the legs 12 is a shaft 14 onwhich are mounted a series of loose band wheels 15 having flanges 16 bywhich they may be moved independently. Mounted on the wheels 15 and thebridge 13 are type bands 17 which may be adjusted manually by turningthe flanges 16. p

The stationary frame (which may be moved manually from place to placebut which is static-nary during the printing action) consists of twosimilar flat plates 18 connected together by tie bolts 19 and screws 20.The plates 18 are provided with upper slots 21 and lower slots 22. Theends of the shaft 14 project into and are guided in the slots 21.Extending through the lower parts of the legs 12 of frame 10 is a secondshaft 23 having its ends guided in the slot 22. Links 24 connected tothe ends of the shafts 14 and 23'by means of screws 25 serves to preventsaid shafts from moving axially with respect to the stationary frame.Collars 26 on the shaft 14 between the sliding and stationary framespreventlateral displacement of the two with respect to each other.

Serial No. 865,440.

Secured on the outer ends of the shaft 23, and adjacent to the innerfaces of the plates 18, are gears 27 which engage stationary racks 28secured to the plate 18. A spring 39 on the shaft 23 acts to turn thegears 27 consequently with respect to the type bands 17 carried in thesame frame that carries the shaft Secured to the outer faces of theupright arms of frame 29, and adjacent to the slots 32, are short racks33 which engage gears 27 (Fig. 3) on the sides opposite racks 28. Itwill be evident that as the spring 39 turns the gears 27 in acontraclockwise direction, as shown in Fig. 3, to raise the stamp frame10 in the stationary frame 18, the racks and pad frame 29 will moveupward twice as fast as the stamp frame moves, and that the slots 32will permit a limited amount of such upward movement. The thickness ofthe pad 31, supported in the box 30 and frame 29, is so related to theother parts that this upward movement of the frame 29 is limited byengagement between the pad face and the type bands 17, and not byengagei'nent between the lower ends of the slots 32 and the hubs ofgears 27. If, with the parts in this upper position, the stamp applyingthe hand to the handle 11 the gears 27 will also be moved downward andwill be rotated by reason of their engagement with they stationary racks28. This simultaneous downward and rotary. movement of the gears 27 willforce racks 33, frame 29 and pad 31 to move downward twice as fast asthe stamp frame 10 and bands 17 move until such movement is arrested byengagement between the upper ends of the slots 32 and the hubs of gears27. The consequence of this action is that when the stamp is manuallymoved downward in the stationary frame 18, the pad 31 moves downwardstill more rapidly to clear it from contact with the type bands. Whenthis downward movement of the pad with respect to the stamp is stoppedby reason of the upper ends of the slots engaging the hubs of gears 27,the said gears and racks become locked together, and thereafter the padframe and pad swing rearwardly upon the shaft 23 as a pivot. Fig. 6shows the position of the pad frame 29 at the time this swingingmovement is stopped by reason of the stamp arriving at the printingpoint.

Secured to the inner faces of the plates forming the stationary frame 18are guides 34; which engage the forward edges of the pad frame 29 whensaid frame is in its upper position as shown in Fig. 3. As the stamprises in the stationary frame, the forward return swing of the stampframe 29 is stopped by engagement with the guides 3st, and thereafterthe pad moves upward twice as fast as the stamp until the entire upwardmovement is arrested by engagement between the pad and the stamp.

lVhen the stamp moves downward in the stationary frame, the pad movesstraight downward at a greater speed until the pad is clear of thestamp. The clearance in the upper parts of the slots 32 is made justenough to have the edges of the pad clear the edges of the type faceswhen the pad swings to the rear. To prevent dirt or incidental frictionin the downward movement of the pad frame 29 from causing this frame toswing to the rear before the desired clearance between pad and type isobtained, the guides 34 are used to maintain this straight downwardmovement of pad frame 29 until the ends of the slots 32 engage the hubsof gears 27. This is accomplished by making the upper ends of thevertical legs of frame 29 arcs of circles drawn from the same centers asthe upper arcs of the slots 32. This permits the free swinging of theframe 29 when the slots are seated on the hubs of the gears, butprevents such swinging until they are so seated. The fitting for thisneed not be very accurate as normally the pad frame will move straightdownward without such guiding.

The pad box 30 is provided with a lip or wing 35 for convenience inremoving it from the frame 29. The box also has small buttons 36 pressedoutward on its ends, which buttons are adapted to fit into depressions37 formed in the legs of theframe 29. The buttons and depressions serveto hold the pad box 30 in the frame 29, while at the same timepermitting the box to be removed by a moderate force manually applied.

What we claim is 1. A stamp, a frame in which the stamp is verticallymovable, a pad pivoted to the stamp and engaging the lower facethereof,and means by which upon manually depressing the'stamp the pad will beauto matically moved downward to clear the stamp face and then will beswung rearwardly out of the path of the descending stamp.

'2. A stamp, a frame within which the stamp is vertically movable, anink pad v pivoted to thestamp and engaging the lower face thereof,.andconnectlons by which upon manually depressing the stamp the pad will bemoved first downwardly more rapidly than the stamp to clear the stampface and then Wlll be moved rearwardly out of the path of the descendingstamp.

A stamp, a frame withingwhich the stampis movable, an ink pad engagingthe face of the stamp, a rack secured to the frame, a second racksecured to the pad, and a gear secured to the stamp and engaging saidracks, said racks and gear serving to move the pad with respect to thestamp when the stamp is moved in the frame.

+l. A frame, a stamp movable in the frame, a pad suspended on the stampand arrangedto engagethe stamp face when said stamp is elevatedin theframe, and

gear andrack connections for removing the pad from the stamp face whensaidstamp is depressed in the frame.

5. A frame, a stamp movable inthe frame, a pad pivoted to the stampand'movablef to engagement with the stamp face, and means by which upondepressing the stamp the pad will be first removed from the stamp faceand then swung upon its pivot.

6. A frame, a stamp movable in the frame,

"an ink pad engaging the printing face of 8. A stationary frame, a stampmovable in the frame, an ink pad, a pad holding frame having a slottedconnection tohthe stamp, a gear on the stamp, and a rack on the padholding frame, said gear, said rack and said slotted connection beingarranged to cob'perate in moving the pad to and from the stamp when saidstamp is reciprocated in the stationary frame. r

9. The combination with a hand stamp, and an ink pad therefoigof a padholding frame pivoted to and arrangedto slide with .respect to saidstamp, and guides for guiding said frame during the sliding portion ofits movement.

10. The combination with a hand stamp, and an ink pad therefor, and aframe within which the stampreciprocates, of gears connected to thesides of the stamp, racks secured to the frame and engaged by saidgears, other gears secured to the pad and also in engagement with thegears, and means by which upon a reciprocation of the stamp in the framesaid gears will turn with respect to the racks on the frame during thewhole of the reciprocation but will turn with respect to. the racks onthe pad during only part of such reciprocation.

11. In a se1f-inking hand stamp, a stamp, a pad engaging the face of thestamp, a bailshaped pad-holding frame pivoted to the stamp, and meansfor moving said frame so is to move the pad from and to the stamp ace.

12. In a self-inking hand stamp, a stamp body, a bai1-shaped framepivoted to the stamp, a removable pad supported in the frame, and meansfor moving said frame so as to move said pad to and from the face of thestamp.

13. In a se1f-inking hand stamp, a stamp body, a shaft extending throughthe stamp body above the stamp face, a swinging frame pivoted upon theends of the shaft, and a removable pad supported in the frame andengaging the stamp face.

14. In a self-inking hand stamp, a stamp body, pivoting points on theopposite sides of the stamp above the printing face thereof, a framemounted upon said pivoting points, and a removable pad-holding boxmounted in said frame.
